To all whom-it may concern:

Be it known that we, WILLIE A. BOYNTON and GEORGE A.

This invention relates to pads and particularly to a new, useful, simple and practical knee pad especially designed for use by cotton pickers.

The aim of this invention is to improve, simplify and render more practical the knee pad illustrated, set forth, and claimed in the patent to Willie A. Boynton of Newcastle, Texas, Patent Number 1,090,446, dated March 17, 191 1.

A further object of the invention is to provide a knee pad which may be provided with one or two cushions, either of which may be stuffed with padding, or provided with a pneumatic tube, in order to support the wearers knee off the bottom of the pad, whereby a thorough circulation of air is maintained under the knee of the wearer.

A further object of the invention is to provide means for easily connecting and disconnecting the cushions.

A further object of the invention is to provide one or more cushions for the pad consisting of a suitable tubular casing to re ceive the padding or a pneumatic cushion, there being a flap covered opening to permit thg insertion ofthestuffing or pneumatic tu e.

A further object of the invention is to provide a U-shaped casing of the design shown in the drawing to receive the cushions, said casing having a metal base, and a fiber upper flange, which may be constructed of any suitable material, either leather or canvas.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings, and claimed.

which may be cut on line 3-3 of Fig. 1, and

instead of showing a stuffed cushion, a pneumatic cushion is disclosed.

Fig. 1 is an enlarged detail perspective view showing the casing 12 with its pneumatic tube.

' Referring more especially to the drawings, 1 designates a U-shaped casing, which 1 consists of the metal base2 having its forward end curved, and provided with a flange 4' upturned from two sides and one end, and the extension flange 3, which may be secured to the flange t of the metal base by means of rivets or the like 5. This extensionfiange 3'1nay be constructed of'any suitable material, preferably leather, and its forward curved portion 6 inclines upwardly and forwardly, thereby providing a yieldable brace for that portion of the leg immediately above the knee, as the wearer leans forward. Secured by rivets 7 to said exten sion flange are the straps 8, which cross each other over the rear part of the leg immediately above the calf thereof, and have their extremities connected to the buckles 9, the leather tabs 10 of which are secured by the rivets 11 to the opposite side of the said extension flange. In Figs. 1 and 2 stuffed cushions are disclosed, but in Figs. 3 and 4: pneumatic cushions are employed. lln Fig. 1 the cushion consists of an outer casing 13, while the cushion in Figs. 3 and 4 comprises a casing 12. In either case the casings 12 and 13 are tubular and U-shaped in plan view to conform to the base 2, and are constructed of any suitable material, preferably canvas. The under portion of the forward curved part 14 of each tubular casing has an opening 15 provided with a closure flap 16, and through which opening, a suitable cushioning means may be inserted in the casing. The casing 13 is filled with some suitable stufing, as shown at 17 in Fig. 2, while the casing 12 contains a suitable pneumatic tube 18, which may be easily inflated by attaching a suitable pump, (not shown), to the extension tube 19, which may be provided with a suitable check Valve, (not shown). However, when using either the stuffed casing 13 or the casing with the pneumatic'tube, the knee is held substantially on a level with the upper edge of the flange 4 of the base plate 2, so as to prevent the knee from contacting with the upper edge of said flange 4: at its forward curved portion, when the leg of the wearer above ward curved portion of the flange 4. The

the knee leans forward. The extension tube 19 extends. through an opening at c one end of the casing 12, so that some suitable inflating means or pump can be atcasings 12 and 13 have side flanges or flaps 19, provided with apertures 20, through which and through the apertures 21 of the extension flange, suitable lacings 22- are passed orthreaded, in order to hold either of the cushioningmembers in place. By supporting the Wearers knee sufflciently spaced up from the bottom of said base plate, a thoroughfcirculation of air may be maintained under the wearers knee.

' The invention having been set forth, what isclaimed as new and useful is:

Ina knee pad, a metal: shoe having an upcopies of this patent'may beobtained finturned marginal flange extending from one side, about the forward end and to the opposite side, a fiber extension flange secured to the marginal flange, securing straps extending from one side of the extension flange to the other and over the leg to hold the pad in place, and cushioning means in the shoe to cushion the knee of the wearer and hold the knee on a plane substantially even with the upper edge of the marginal flange, said cushioning means consisting of tubular Ushaped casings, means to secure said tubular U- shaped casings to the extension flange, said tubular U-shaped casings having flap covered openings, through which the cushioning filling may beinserted into said casings.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
